Application led March 20, 1916. Serial No. 85,477.

all whom may concern:

Be it vknown that I, Josnrironsos, .a subject of the King of Hungary, residing at Columbus, in the l county of Franklin and State of. Ohio, have invented certain new and useful Improvements' in Safety-Envelops, of which the following is a speciication.

This invention relates to certain new-and useful improvements in safety envelops.

An object of the lnvention is to provide a safety envelop formedof a blank including ,enfolding sections that are intel-locked and gurnmed so that it`will be impossible for unauthorized persons to gain access to the con'- 'tents thereof without in some manner injuring the envelop or indicating that the same has been tampered with.

With these Ageneral objects in view and .others that will appear as'the nature of the invention is better understood, the same consists 1n the novel construction, combination and arrangement of parts hereinafter Amore fully described, yillustrated in the accomf ,'panylng drawings, and then'claimed.

In the drawings forming a part of ythis application and in ywhich-like designating characters refer to corresponding parts throughout the several views Figure 1 is a plan view of the envelopv blank constructed in accordance with the present invention.

Fig. 2 is a plan view of the same with `the# lower 'blank sectionand one of the side iiaps Fig. 3 is a plan view of folded inwardly. the envelop with both side iaps folded inwardly, with the slots in the side flaps superposed. Fig. 4 is a plan view of the envelop with the sealing flap carried by the lower blank section interlocked and gummed to the side flaps. Fig. 5 1s a planview of the envelop in completely closed position. Fig. G

' yis a vertical cross-sectional view taken on line VI-VI of Fig. 4, with the sealing Hap moved to an angular position, and, Fig. 7 is a vertical sectional view taken en line VII- VII of Fig. 5, showingy the position of the sealing Hap tongue when the envelop is in completely closed condition.

Referring more indetail to the acco1npanying drawing, the reference numeral 10 designates the main body-portion of the envelop blank which constitutes the vfront wall of the envelop while a lower blank section 11 is carried thereby and forms the rear-wall of the envelop. Side flaps 12 and 13 are carried by the ends of the body-portion 10 and SAFETY-ENVELOP.

are preferably of the configuration shown in plan view in Fig. 1, achside flap being slotted as at 14.- with the slots so positioned that whenvthe side iiaps are folded inwardly 6o "in overlapping relation andsuperposed'relative to the body-portion 10, the said Slots A will register as indicated in Figs.' 3, Gand "1'.

A substantiallytriangular extension 15 is carried by the outer edge of the lower blank section 11 and is provided at the outer end vthereof with a sealing tongue 16, the inner face of which is gummed as at 17 while the rear face thereof is gummed as at 18 as indicated in Fig. 3. A folding cover flap 19 70 is carried by the opposite side of the body blank 10 and is provided at the outer end thereof with a gummed sealing tongue 2G.

In order vto fold the envelop blank shown in Fig. 1 to the position shown in Figs. 5 7 5" and`6,^the lower blank section ligislfolded o fupwardly on the creased line to' cause f 'the blank sections'lO and 11 to lie juxtaposed, and after`which the? side-flap 12 is folded inwardly `on the line eB- as shown 'A in Fig. 2. Thecpposite' side flap 13 is then folded' inwardly on 'the' creased line-0* flaps 12 and 13 to lregister as indicated in Fig. 3.`4 The lower curved 'edges of the side flaps 12 and 13 aregurnmed as at 21 for adhesively engaging the blank bottom/'section 1.1. By folding the triangularv extensionl 15 carriedfby the lower blank `s'ection'll ori-the creased line -a-,'the gummed surface 18 90 Y of the tongue 16is caused to adhesively en gage the outer face of the side iap lwhile' the end of the tongue passes through the yregistering slots 14 in the side flaps and has the gunnned .portion 17 thereof adhered -to 9'5 the inner side of the side flap 12 as indicated' u in Fig. In .this position, the matter to be inserted into the envelop may at this time beintroduced and the lcover iiapsection 19 folded on the line -e-. to bring the gurnmed 100-` section 22 into adhesive engagement with the side flaps 12A and 13. ,The gurnmed tongue 20 is then passed upwardly beneath the lower edges of the side flaps-12 and 13 to a position to lie 4between the side flaps and the 105l vlower blank section 1l as is indicated in Fig. 7 and to; be gummed .at this point to the said side flaps. v From the above detailed description of the invention, itis thought that the construction and operation thereof will be readily apparent, and while theforrn'of the invention herein shown and described is what is believed to be the preferred embodiment, thereof, it is nevertheless to be understoodthat various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is An envelop formed of a blank including a main body portion, side flaps carried thereby and having slotted openings adj aeent to their ends and arranged to register when the 11a ps are folded inwardly, the lower edges of the flaps haring curved gummed edges and the portions having the slots being of substantially rectangular contour, a lower blank section carried by the main body-portion ing gun'nned, the gummed tongue carried by the triangular extension being adapted to be the cover fiap being adapted to be moved to a positlon. between the lower blank Section and the side iaps and be gummed to the latter,

In testimony whereof I affix lny signature.
